  • Patent number: 9757132
    Abstract: A device has been developed to augment the rotator cuff tendon tissue as it proceeds in healing. The device has two purposes: to provide initial stability to the rotator cuff repair site to allow early mobilization of the upper extremity of the patient, and to allow for reinforcement of rotator cuff tendon repairs to increase the likelihood of successful rotator cuff tendon repairs. The device consists of an inter-connected, open pore structure that enables even and random distribution and in-growth of tendon cells. The braided structure allows for distribution of mechanical forces over a larger area of tissue at the fixation point(s).

  • Patent number: 8758437
    Abstract: A multi-region device for repair, regeneration or reconstruction in articular tissue injury such as torn ligaments and tendons is provided. The device comprises at least one degradable material and biocompatible non-degradable polymeric fiber-based material, in a three-dimensional braided scaffold. The two end sections are designed for attachment of the device at the site of implantation and are designed to allow bone cell ingrowth, and one or more middle regions are designed to allow ligament or tendon cell ingrowth.

  • Patent number: 8545927
    Abstract: The invention provides biomatrix compositions comprising cross-linked lactoferrin, either alone or in combination with other organic or inorganic components. Also provided are methods of making and using the biomatrix compositions. As described herein, cross-linked lactoferrin biomatrix retains the bioactivities of the lactoferrin molecule. The biomatrix composition can act as a matrix for cell adhesion and growth and is particularly useful in musculoskeletal tissue regeneration. The biomatrix compositions can be pre-formed or injectable and can act as a cell, drug or protein delivery vehicle.

  • Publication number: 20090005869
    Abstract: A device that is secured inside a human or animal joint. The device may include, but not limited thereto, the following components: 1) eyelets for suture; 2) endcaps; 3) a longitudinal core; 4) optional additional longitudinal members; and 5) a space for carrying a payload of controlled release drug. Numerous preparations of controlled release drugs have been proposed. This device acts as a platform for said preparations and drugs. It is distinguished by, among other things, its geometry and structural elements which are optimized for: 1) surgical passage into a joint; 2) stable attachment inside of a joint; and 3) secure carriage of the payload device for controlled release of drug.
